External Antenna for a DLink DWL-610

The DWL-610 only has an onboard antenna, and no connector for an external one. We manually add one. Little documentation about hooking a pigtail on a DLink DWL-610 exist. Based on the more widely available information to do the same for DWL-650(+) models, we try to do it on ours.

Open the Case

The case is openned by first removing the metal plates making the case.

Removing the outside plates

The easiest to do so is to slide a knife in the gap on the sides. The plates are interlocked, but it only take a small lever effect to take one out of the other's rail.

By means of the same knife, the back of the antenna case can be extracted.

The final bit of the case can then be removed.

...and the rest of the case

The DWL-610 has two internal antennas. Unfortunately, it doesn't have any connector to hook up an external one. Things will get dirty…

Add the Pigtail

The pigtail will be installed in place of the first antenna (the one without the resistor). To avoid interferences, it seems — according to various other sources — that the actual on-board antenna has to be disconnected. This is done by cutting off both connections to the rest of the board.

The internal antenna is disconnected

Two connections points have to be cleared for the pigtail, one on the antenna line and the other on the groundplate.

The connection points are created by scratching the plastic They are then coverred in solder to ease later installation of the pigtail

The pigtail had an UF.L connector, which wasn't really useful. It's been cut off. The coax cable of the pigtail then has to be prepared to be soldered. The line and ground first have to be separated, which may not be as easy as it sounds as the ground was platted around the line in two separate layers, and everything is quite small.

Much better separation Once again, the cables are coverred in solder to help future soldering

The two cables are then affixed to the board. It is important to make sure there is no contact between both. It seems that, to direct current, both sides of the antenna are connected to the ground of the board, so a continuity tester is not of much help here…

The pigtail soldered to the board

As the cable is dangling a bit too dangerously, it threatens to pull on the board and risks disconneting over time. The cable will be secured with a snaplock. It is necessary to create some holes where the now useless on-board antenna is to support the lock.

Final Tweaks

The pigtail now being properly secured, the board can be put back into its case. Due to the modifications, though, the case has to be adapted a bit.

After closing the case, the card looks quite clean.

Tests

The antenna can now be installed in muDrublic.
